What is a thesis/argument that John Cheever makes in his short story "The Enormous Radio"?

Written by John Cheever in 1947, “The Enormous Radio” focuses on Jim and Irene Westcott. Combining elements of magical realism and the domestic gothic, the story’s thesis focuses on buried secrets. When the couple’s radio breaks, they order a new one and soon find out that it allows them to listen to their neighbors’ conversations. In listening to other people’s marital issues, the Westcotts begin to recognize the tension in their own marriage. “We’re happy, aren’t we darling? (Irene) pleads to Jim.” Of course, the Westcotts aren’t happy; they’re simply well versed in playing the part of a happy, status driven, financially secure couple. The radio is the fantastical tool that brings to light Jim and Irene’s secrets and accrued grievances. Cheever is arguing that no matter how strong a façade a married couple has, neglect, denial, and a lack of communication poisons a marriage.
